Wesley T. Huntress Jr.,Mikhail Ya. Marovof images characteristic of the imaging process in the absence of noise and by examining the properties of object inventories for a test field digitized at a range of sampling intervals. Both analyses indicate that 15μm is an adequate sampling interval for modern Schmidt plates on Type III emulsions.令人苦恼 发表于 2025-3-24 09:34:05
